This is what I've been searching for. I've been trying to search why my system is all screwed up, why I couldn't put things into systems after creating my complicated web of lies. I had done it in the wrong order. No other tutorial showed this 'obvious' thing. I didn't know that I didn't know about this 'obvious' thing. Thank you. Now, I need to recreate a 8 story HVAC building.. yay.
Sure will do. Would it be possible for you to give some guidance on how to start learning Revit, I will use it for ventilation system design, where shall I start? Is there some learning sites, boks? I appreciate your time and effort dear, thank you a lot.
The most effective way to learn Revit is to be taught by a certified instructor who knows how to teach well. You can look at websites, books, youtube, etc. and that should help. My videos are point specific so learning Revit via my youtube videos is a great start. I also have tons of resources I created so you can access them for free: look me up on Linkedin, Twitter, Autodesk Screencast, Autodesk Knowledge Network, etc. Lastly, I can always teach you what you need to learn. Depending on your timeframe and budget, we can work things out. Hope this helps.
Very well advice, thank you. Please add me to your LinkedIn friend list, so we can discuss it further in private. I couldn't add you there. Thanks again.
no worries...if you go to linkedin...search for Dzan Ta and click to request joining my list of network contacts, I can then add you. If you give me your full name I can search for you within Linkedin to add you....couldn't do it with just North Star.
I have high static pressure on a new 3.5 ton heat pump. I know for sure the flex duct is the issue. I have two 12" coming out of the supply in opposite directions. I know I need an 18" for a 3.5 ton heat pump. I did a diagram layout of the duct in the attic. What would happen if I just replace the two 12" to 18"? Ignoring the downstairs, because everything is between the walls. The problem was even worse with an undersized return. The original and only return was a 24x18. The total static pressure on the unit was .9 W.C. I was able to drop the TESP to .66 by making the return 30x24. Since there is so much static pressure and the unit TESP is a .2 and I need an 18" for a 3.5 ton for 1400 CFM. How big does the supply plenum should be and what shape? Should the supply plenum split to 3 18" going out to each of the 3 distribution boxes? Do the other three distribution boxes also need to be larger? Looking at the triangle shaped supply plenum I have very little room up for a rectangle plenum. I think a 3 feet ductboard supply plenum should work. There is a foot from the Air handler to the ceiling and I think 2 feet from the attic floor to the roof. Now I am looking at two types of designs. Design #1 keeps the 18" ducts straight by having a single 18" coming out of the supply and then a distribution box splitting it to three 18". The sides would be coming out straight to the to side boxes and one going to the third box with a slight curve. Design #2 splits to three right at the supply plenum and goes to each box individually, but all three will have a slight curve. I will not be using any metal plenums..... it will be all flex duct and ductboard boxes, because of budget. I am not trying to make a perfect system, but trying to remove the restriction from the 12" undersized ducts installed and replacing the flex duct that was patched with mastic with new ones. Another question about the installation..... I have the flex duct running up and strapped to the roof for support. Since the supply plenum is low to the floor due to the roof..... Can the flex duct be run on the attic floor? Can you tell me which layout makes more sense and less restrictive? Thank you.

Hi Danny. I am sorry but I am not a mechanical engineer. You will need to get with an ME who knows revit that can help you. Try to speak to Andrew's Hammock and Powell MEP engineers out of Macon, GA. They are an excellent group of engineers whom I have taught Revit. They can help you further.
sorry....missed this somehow. You will need to start with the a Revit family template file such as mechanical fitting. Then, build the geometry using standard family building practices. See my other family creation series videos to understand how to built this family. If you still need help, just let me know...
If you are a mechanical engineer who knows all the components needed, you can build the complete system. My background is architecture so I don't know all the necessary components for a complete mech system.
Haider Shaker The duct accessories and fittings are part of the Imperial or Metric library already istalled on your machine when uou installed Revit. If you want to use manufacturer specific familes, go to thwir website or call them. The families in Revit are generic and a good starting point.
Hi....You can add any connector to the family by using the commands located in the Ribbon. Choose a connector command, place it on the face of the family and then adjust the properties of the connector in the Properties Palette. Sorry, but I do not make families to sell.
@@DzanTa Cant do, I want repeat what you did in 4:22 take the duct system and go back to the unifilar layout. In the contextual ribbon I get Duct System instead of Generate Layout
@@DzanTa finally I got it, I wasn't paying attention to your explaination, Happens you need to have your air terminals into a system otherwise the layout option wont be available or simple wont appear into the ribbon, thank you very much again sir.

Nicely explain...
Can you explain how to make Wye duct connector?
sorry....missed this somehow. You will need to start with the a Revit family template file such as mechanical fitting. Then, build the geometry using standard family building practices. See my other family creation series videos to understand how to built this family. If you still need help, just let me know...
Do you create the whole system such as attic furnace, outdoor A/C compressor unit being hooked up to the house?
If you are a mechanical engineer who knows all the components needed, you can build the complete system. My background is architecture so I don't know all the necessary components for a complete mech system.
how did you get to this point from a blank set, so i can practice
I started a new revit project based upon the Mechanical Template.rte file
Hi friend good works ,so .please can i get the flange, bolts and valves library or family ..thanks

how to automatic conectors like elbow and reductions ? Are you sell this families to dowload?

Dzan Ta thank you by the answer. Now I can put the diffuser but I don't have more conecctors..I I'll search the other families, thanks
Once the ducts are created how can you go back to the layout edition
Tab select the entire duct run and use the contextual Ribbon to edit the layout
@@DzanTa Cant do, I want repeat what you did in 4:22 take the duct system and go back to the unifilar layout. In the contextual ribbon I get Duct System instead of Generate Layout
@@luisb2253 that means the system wasn't created properly or the component lost its association to the system. You will need to recreate the system.
@@DzanTa thank you very much sir, I'll keep trying
@@DzanTa finally I got it, I wasn't paying attention to your explaination, Happens you need to have your air terminals into a system otherwise the layout option wont be available or simple wont appear into the ribbon, thank you very much again sir.
How to delete this automated routing from drawing?
You can tab select the entire system and then use delete
